How to Paper Trade on Composer
In this article, you'll learn how to paper trade a symphony on Composer with our Alpaca API integration.
Connecting to Alpaca
The first step is to connect your Composer account with your Alpaca account. If you don’t have an Alpaca account, you can set one up for paper trading from anywhere in the world.
In Composer, head over to the menu with your name on it and select “connect to Alpaca”.
Next, authorize Composer to access your account information and to place transactions in your Alpaca account. By agreeing, you grant Composer permission to place paper and live transactions in your Alpaca account, following the symphonies in your Composer account that you assign to Paper Trading and Live Trading, respectively.
Wait for the authentication, and you’re ready to go.
Setting a symphony to paper trading
For now, you can assign a maximum of one symphony to execute in your paper trading account on Alpaca. To do that, open up the symphony in the Editor and change the status of the symphony from Testing to Paper Trading.
Note: Symphonies can only be set to Paper Trading while the market is open (typically 9:30 am to 4 pm EST on weekdays).
The assets making up your symphony will be bought and sold according to the specifications of the symphony at the trading frequency you specified (i.e., daily, weekly, etc.).
If you have a symphony set to Paper Trading and then set a different symphony to Paper Trading, the symphony previously set to Paper Trading will be moved to Testing (i.e., that symphony will only exist in your Composer account).
